GAS HEATER.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed February 21, 1920. Serial No. 360,427.

To a "whom it may concern:

Be it known that I, WV LLIAM C. HERBERT, a citizen of the United States, residing at- Brooklyn, in the County of Kings and State of New York, have invented new and useful Improvements in Gas Heaters, of which the followin is a specification.

Thisinvention relates to gas stoves and has for its primary object the provision of an improved burner construction which will permit of complete combustion of the gas and 7 enable the stove to be economicall operated.

Another object of the invention is to provide a device of the above described character which will be simple of construction, strong and durable, and one in which several novel features of construction are combined so as to permit heat of great intensity to be produced with an elimination of noxious gases.

With the above and other objects in view which will appear as the nature of the invention is better underst'0od,-the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out inthe claims.

In the accompanying drawings has been illustrated a single and preferred form of V the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

Figure 1 is a longitudinal section through the stove.

Fi ure 2 is a section taken on the line 2-2 of Flgure 1.

Figure 3 is a view similar to Figure 1 showing a slightly modified form of the invention.

Figure 4 is a section taken on the line 4-4 of Figure 3.

Figure 5 is a section taken on the line 55 of Figure 4.

In carrying the invention into practice, use is made of a casing 10 or outer shell which can be constructed of foraminated sheet material, the said casing closed at its top by a cap 11. At the base, the casing is provided with a plate 12 flanged at 13 beyond the sides of said casing or shell and, as illustrated, said flange has secured thereto .degrees or approximately so.

suitable supporting legs 14 which operate to hold the base of the casing spaced from the floor or other support upon which the stove is mounted. The base plate 12 is provided with a relatively large draft opening 15 which opens into the casing beneath the burner 16.

Said burner is in the form of a perforated pipe, the same extending from one end of the casing 10 to the other end thereof. One end of the pipe is closed by a cap 17 The other end is extended through the adjacent end wall of the casing and it is connected with a supply pipe 18 by means of which illuminating gas may be delivered to the burner. The pipe 18 is preferably provided with an air mixer, the same conventionally illustrated at 19 and may be of any well known construction.

Above the burner is a baffle member 20 which is flanged at its sides at 2121. Said bafile is mounted upon an adjustable spring bracket- 22 and "connected with the bracket is an arm 23 adapted to co-act with one of the perforations in the casing 10 so as to hold the bracket relatively fixed in any one of a plurality of positions. This construction is such that an air space or chamber is defined by the walls of the battle member and an area of the space can be regulated so as to permit a proper volume of air to be mixed -with the gas and thereby insure proper combustion and production of a blue flame. The perforations 24 in the burner 16 are preferably arranged at an angle of 45 The bafile member has its top wall directly overl ing the burner so that as the gas escapes rom the perforations 24 it is made to impinge against the under surface of the top Wall of the baflie member, the gas taking the course illustrated by the dotted line A. It then rebounds and takes the course indicated by the dotted line B and it impinges against the inner face of the adjacent flange 21 of said bafiie member. Through this arrangement, and from the fact that the baflle memher is adjustable so that the air space above the burner can be regulated, it obviously follows that perfect combustion results and that a blue flame will be produced at the burner. The baflle opens downward and spaced from the baflle and curved from a point slightly below the burner to a point to the top of the casing 10 is a deflector 25 which operates to cause the heat to be distributed from the front wall 26 of the casing.

The construction above described is suchthat in some instances I find that the mixer 19 can be entirely eliminated andthat the bafliemember acts as more than a substantial substitute therefor. By regulating the.

amount of air in proportion to the volume of gas, directly at the burner, the flame is uniformly blue and a mixture of air and gas is provided for which will enable one to perate the stove economically.

In the form shown in Figures 3 to inclusive, the baflie member 26 is of cruciform shape and the same overlies a burner 27 of corresponding formation. In this instance, the burner has each of its branches provided with a double row of perforations 28. The baffle is fixedly positioned with respect to the perforations. The said battle is also arranged so that both side flanges 29-29 are utilized for the impingement of the gas there-against. This construction provides a combustion chamber above the burner, and the products of combustion are retarded by the action of the baflie by striking the main" portion of the plate and being deflected to -ously referred to.

the side plates-29 for distribution throughout the portions 30 and 31 of the chamber formed by this baflie, for thorough mixture with oxygen so that an effective combustion chamber is provided. The gas, as it leaves the perforations 28 takes the same course with respect to the baflie member as previ- What is "claimed as new is:

1. The combination with a gas burner, of a baflle comprising an inverted substantially U-shaped member arranged above and I partly embracing the burner and designed to forma combustion-chamber and means for adjusting the U-shaped member with respect to the burner.

2. The combination with a gas stove and ber arranged above the burner and designed to form a combustion chamber, means disposed to one side of the burner for supporting the latter upon the casing of the stove and means whereby the supporting means may be moved to adjust the member With respect to the burner. V

3. The combinati'onwith a gas stove and a burner therefor, of an imperforate member arranged above the burner and designed to form a combustionchamber, an arm having one end connected'to one side edge of the, 'lmperforate member and the other end socured to the casing of the stove and means whereby the arm may bemoved to adjust the member with respect to the burner.

4;. The combination with a gas stove and a burner therefor, of an imperforate mem ber arranged above'the burnerand designed to form a combustion chamber, an arm having one end connected to one side' edge of the imperforate member and the other end secured to the casing of the stove and means connected to the arm and co-acting with the casing of thestoye, whereby the arm may be moved toadjust the member-with respect to the burner.

5. A gas heater comprising a casing hav-" 7mg perforated walls, alongitudinally exand to one side of the chamber to provide a passage between said chamber and baffle wall and means whereby the member may be adjusted relatively to the burner to regulate the area of combustion and'maintain substantially the same passage'cspace.

In testimony whereof I have aflixed my signature.
